I am a newbie to install Oracle. I need to install Oracle XE 11g. I checked it on Oracle, there is only Oracle Database Express Edition 11g Release 2 for windows x32. My operating system is Windows 7 64 bits. So I am concerned if there can be potential compatibility problem. Is there Oracle XE 11g for 64 bits windows (Or does it matter to work with OC4J 10g oc4j_extended_101350 and APEX 4.1 listener)? Considering I will have to install OC4J and Oracle APEX listener. I am worried about this compatibility problem more. (I have installed OC4J 10g (oc4j_extended_101350) and installed it as a windows service with javaservice application, it spent me a lot of time to solve compatibility problem)
